Project description:The Tasmanian devil, a marsupial carnivore, is endangered due to the emergence of a clonally transmissible cancer known as Devil Facial Tumor Disease (DFTD). This fatal cancer is clonally derived and is an allograft transmitted between devils by biting. We performed a large-scale genetic analysis of DFTD with microsatellite genotyping, mitochondrial genome analysis, as well as deep sequencing of the DFTD transcriptome and miRNAs. These studies confirm that DFTD is a monophyletic clonally transmissible tumor, and suggest that the disease is of Schwann cell origin. On the basis of these results we have generated a diagnostic marker for DFTD, and identify a suite of genes of relevance to DFTD pathology and transmission. We provide a genomic dataset for the Tasmanian devil, which is applicable to cancer diagnosis, disease evolution and conservation biology. This submission contains only small RNA sequence data from this study.

Project description:The histocompatibility barrier prevents transmission of both normal and tumour cells between individuals 1, however clonally transmissible cancers in dogs, Tasmania devils and soft-shell clams can naturally transmit as allografts 2. To understand how tumours can escape the histocompatibility barrier, we have serially passaged a mouse melanoma first into syngeneic mice and then into progressively more mismatched mouse strains until a fully allo-transplantable tumour emerged. Here we show that tumour passaging selected for cells with an anti-viral inflammatory signature, characterised by expression of MHC-I, PD-L1, Qa-1 non-classical MHC molecules and the upregulation of intergenic endogenous retroviral elements (ERVs). Knock-out of RNA sensor RIG-I 3 in the transplantable tumour cells resulted in reduced expression of MHC-I, PD-L1 and Qa-1. Antibody-mediated blockade of both PD-L1 and Qa-1 induced tumour regression after transplantation. A similar inflammatory signature was found in human melanomas that respond to anti-PD1 antibody treatment. Thus, an inflammatory anti-viral signature likely induced by RIG-I sensing of ERVs facilitates escape of the mouse melanoma from allogeneic rejection. The results underscore the immunological plasticity of melanoma and reveal an unanticipated role for inflammation in allograft immune evasion.

Project description:The goal of this study is to identify m6A targets in human CD34+ HSPCs with or without STM2457 treatment using DARTseq. Purified human CD34+ HSPC cells were transduced with APOBEC-YTH or empty vector control (MIG). 24hr post infection, CD34+ cells were treated with STM2457 at a concentration of 20µM for 2 days. GFP+ cells were sorted the next day. 3 replicates were performed.
